The role of storage technologies for the transition to a 100% renewable energy system in Ukraine

摘要: Abstract A transition towards a 100% renewable energy (RE) power sector by 2050 is investigated for Europe. Simulations using an hourly resolved model define the roles of storage technologies in least cost system configuration. The are batteries, pumped hydro storage, adiabatic compressed air thermal and power-to-gas technology. Modelling proceeds from 2015 to five-year time steps, considers current plant capacities, their corresponding lifetimes, projected electricity demand determine optimal mix plants needed achieve RE 2050. This optimization carried out with regards assumed costs technological status all involved. total capacity required 2050, shares resources, defined. Results indicate that levelised falls level 69 €/MWhe 51 through adoption low generation, improvements efficiency, expanded interconnections. Additionally, flexibility stability provided increasing solutions over time, parallel expected price decreases these technologies. Total requirements include up 3320 GWhe 396 218,042 GWhgas gas (8% synthetic natural 92% biomethane) period depending on scenario. share increases less than 2 €/MWh (2% total) 16 (28% same time. Outputs begin 2020 when generation reaches 50% system, 44 TWhgas can be more economical efficient solution Europe, one also compatible climate change mitigation targets set Paris Agreement.
